ASSAYERS POURING-MOLD.

To all whom t may concern/:

Be it known that I, JOHN J. BAILEY, a citizen of the United States, residing at Victor, in the county of Teller and State of Colorado, have invented certain new and useful Improvements in Assayers7 Pouring-Molds; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom anying drawings, and to the letters and gures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in assayers pouring-molds, my object being to provide a mold of this class adapted to facilitate the separation of the metallic portion of the contents ofl the mold from the slag or lighter portion. Heretofore, so far as I am aware, molds of this character have been provided with conical receptacles. In this case when the molten mass containing the flux and ore is poured into the receptacle of the mold the metallic portion being heavier settles to the bottom, while the lighter portion or gangue remains above. In separating the metalhc portion from the gangue considerable difficulty is experienced from the fact that the gangue clings to the metallic portion.

In my improved construction I provide two compartments-one for the metal and the other for the gangue-the said compartments, however, communicating with each other by a reduced orifice. The contents of the mold may then be easily separated at the reduced part or neck intermediate the two members.

Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the accompanying draw" gs, in willich is illustrated an embodiment therebf.

In the drawings, Figure l is a top plan view of my improved pouring-mold. Fig. 2 is a longitudinal section of the same. Fig. 3 is an underneath view of the mold proper. In this 'case the body of the mold is turned over and its top surface rests upon the ba'seplate. Fig. 4 is a cross-section taken through the mold member proper, cutting one of the receptacles for the molten material. Fig. 5 is a detail view of the contents of the mold after it has become hard and the metal obtained has been broken from the upper or slag portion.

The lsame reference characters indicate th same parts in all the views.

Let the numeral 5 designate the body of my improved mold, which when in use rests upon the base-plate 6. The body of the mold is composed of a series of receptacles 7, each composed of compartments'S and 9, the compartment 8 communicating at its bottom or lowest point with the upper reduced extremity of the compartment 9. The compartment 8 is cup-shaped, having curved walls interrupted only by the small orifice l0, communicating with the compartment 9 lthe latter being cone-shaped or having the shape of the frustum of a cone. It must be understood that the shape of the compartments 8 and 9 may be varied without departing from the spirit of the invention. Each mold may be provided with any desired number of receptacles, six being shown in the drawings.

When the mold is in use, it is placed upon the base 6, with the compartment 9 lowermost. After the ore from which the values are to be extracted has been mixed with the necessary flux and reduced to a molten condition it is poured into the receptacle 7. The values or metallic portion to be separated from the crude material or gangue being heavier pass downwardly into the compartment 9, while the lighter or gangue portion occupies the compartment 8. As soon as the contents ofthe receptacle becomes cold it is only necessary to tap the member A of the contents-of the mold with a hammer in order to cause the member B to break off and drop out of its compartment, In this way a more nearly exact separation of the member B from the member A is effected than can be accomplished where the molten mass is poured into a single compartment.

Having thus described my invention, what I claim isl. An assayers pouring-mold provided with a receptacle containing two compartments communicating with each other by a relatively small orifice.

2. An assayers mold provided with a receptacle composed of two compartments of unequal size, communicating with each other by a relatively small orifice.

3. An assayers mold provided with a receptacle composed of two intercommunilOO IIC

' the smaller compartment by way of a relatively Small orifice.

6. An assayers pouring-mold provided with a pluraliity of receptacles, each consisting of two intercommunicating comparte ments of unequal size, tbe larger compartment being uppermost.

In testimony whereof I allor my signature in presence of two witnesses.
